Re: Acer-WMI disables touchpad and other issues

["Nathanael D. Noblet" <nathanael@gnat.ca>]

So far I've added the options acer-wmi ec_raw_mode=1 to a modprobe.d 
conf file. Looking at /sys/modules/acer_wmi/parameters/ec_raw_mode 
contains a Y. The mousepad remains unresponsive on boot prior to a 
Fn+F7. I've added options acer_wmi ec_raw_mode=1 (note the acer_wmi vs 
acer-wmi) simply because the sysmodule was also underscore. There is no 
difference, the module parameter is recorded as Y and the mousepad still 
does not work on boot.

I will provide the other requested information soon.
